Application June 7, 1947, Serial No. 753,255

5 Claims. (Cl. 134-104) This invention relates to a dish washer andarticle intercepting drawer therefor and, more particularly, it relatesto a corner dish washer containing a removable refuse catching tray.

In my United States Patent #2,353,993, issued July 18, 1944, and myco-pending application S. N. 739,705, filed April 5, 1947, now PatentNo. 2,573,128, dated October 30, 1951, I have described dish washingunits containing traps for selectively catching waste material andcutlery. Said traps are easily removable from the units and do notinterfere with the units while in op,- eration.

An object of the present invention is to provide unique improvementsover those indicated in the hereinabove noted constructions.

Another object of this invention is to permit the flow of Wash and drainwater in a dish and cutlery washing unit while preventing the loss ofsmall objects which are being washed and drained.

One other object of the present invention is to provide an easilyconstructed, drawer trap adapted to catch small objects and direct theYflow of wash fluid from the trap.

A further object of this invention is to provide a withdrawable trapunit for a dish and like washing machine, said unit having a drawer,drip means and perforated catching means.

' A more specific object of this invention is to provide a drawer unitWhose structure is such that it contacts all the walls of the unit inwhich it is inserted.

Further objects and advantages oi the present invention will becomeapparent from the following description taken in connection with theaccompanying drawings in which:

ig. 1 is a horizontal, sectional view of a preferred embodiment of myinventionk taken on line I-I of Fig. 2;

Fig. 2 is a perspective View of a dish washing machine containing myinvention;

Fig. 3 is a plan view of a corner drawer for use in a dish washing unit;

Fig. 4 is a sectional view taken on line 4 4 of Fig. 3 of a cornerdrawer as retained in the dish washing unit; and

Fig. .5 is a perspective view of the drawer frame shown in Fig. 4 withfront exterior part removed.

Referring now to the drawings in which like reference characters denotelike parts throughout, there is provided a dish and cutlery washing unitIE5 of the ordinary type, as shown in Fig. 2, and which is used in thekitchens of restaurants, homes and the like. Said unit contains aplurality of spaced vertical supporting legs, II, I2, I3

and I4, respectively, on which is mounted a lower platform I5 supportinga motor and pump unit I5 in communication with a water basin section I1as shown more clearly in Fig. 1.

Said basin or water chamber section II is provided with the usual typeof hot and cold water connections, I8 and I9, respectively and which arecharacteristic of dish washing machines, a drain and overow line 20 withcontrolling valve, and a rinse valve 2I, as shown in Fig.. 2. The watercontained in said 'chamber I'I is heated by any suitable means, such asa gas unit 22, disposed beneath said water chamber I'I.

Disposed above waterchamber I1 is a plural ity of horizontal perforatedpipes 25 in connection with motor and pump unit It. Above said pipes 25is an open platform or bracket 21 on which are placed Wire ytrays ofdishes, cutlery and other washable items used in restaurants, kitchensand the like. V

Provided above said bracket 2 is spray chamber 25 consisting of walls 28', 29, 30 and 3l, respectively, which are extensions of the middleportion forming the water chamber I1. Two of said walls 28 and 3|comprise vertical moving partitions for permitting the insertion andremoval of trays containing dishware, cutlery, etc. Said partitions 2Band 3| may be of glass to permit observation of the cutlery and dishwareduring the washing operation.

It will be noted that, disposed above the water chamber I'I, there isprovided a sloped flooring 23 having an opening 24 to permit the returnof water into water chamber I'I from spray chamber 25.

Beneath said floor 23 and the spray pipes 25, there is provided a drawer32 preferably of a polygonal shape, as shown in Figs. l, 3, 4 and 5.Said drawer 32, because of its form, extends through the diagonal ormajor length of the spray chamber 25 so as to facilitate the catching ofal1 waste material and also of any small objects which may tend tobecome loose from the trays and escape towards the water chamber. Saiddrawer 32 comprises an integral, hexagonal shaped frame 33 containinglong side members 34 and 35,' respectively, and opposed diagonallydisposed short members et, 37, 38 and 3S, respectively, all of which,for purposes of illustration, are of right angle construction. Saidshort members 36 and 31 t flush against the walls 29 and 39 of the waterchamber while long arm members 3d and 35 are radapted to slide on rails40 and 4I set in the compartment intermediate the spray chamber andwater chamber' I1. Short members 38 and 39 are provided with attachedextending flange members 42 and 43, respectively, which act asa stopagainst the walls 28 and 3l of the water chamber i7 when the drawer isinserted into the intermediate chamber 44. It will be noted that saidlatter members i2-43 are provided with a handle as shown in Fig. 3 topermit the withdrawal of said drawer 32. Said drawer has a dependingportion 45 as shown in Fig. 4. It is furthermore provided with a driptray member t5 hinged at its forward end portion di' to the drawer 32,as shown in Figs. 1, 3 and 4, and has an upwardly flanged portion 46adapted to t snugly against depending ilange 45..

Tray 46, it will be noted, extends the major portion of the drawer frame32 and is adapted to drop downwardly. as shown in Figs. 4 and 5, topermit the flow of waterV from pipes 25 through the opening 24 andintowater chamber il. Said drawer 32 is provided with 'a pair ofremovable, perforated baskets, i8 and 49, each of which corresponds toone-half the` length of the drawer frame as shown in Fig. 3. It is to benoted that, in lieu of having perforated baskets, as shown, a singlecomplete basket may be used having substantially the same shape as thatof the drawer frame.

The downwardly extending portions of walls 28 and 3| forming part of theintermediate chamber 44 and washing chamber l1 are provided with dripgutter disposed beneath the external or flanged portion of the drawer,as shown in Fig. 2. Saidgutter 5B is adapted to collect an;r

moisture that may seep from the drawer lramo and permit return of thewater into the water chamber through-the openings iii in walls of thewater chamber.

It will be noted from the description and aci:

i9 on dra-wer 32 in intermediate chamber ed.

Any leaking water from the iront of drawer 32 collects and is guided bysaid drip tray gutter Eii through openings 5l into the water chamber l'.Any solid items that may escape from the dish trays will be collected onthe perforated Y baskets and are easily recovered.

To remove cutlery or similar objects collected in baskets d@ and 4B,said drawer 32 may be easily removed from the intermediate chamber byraising handle 45 until the forward, upper portion of the frame 33, asshown in Fig. 4, reaches its limit of upward movement. The handle 45 israised in orderV to lift the lower front corner of tray 45 above thelevel of the lower edge o the opening through the corner 0f chamber I9.The drawer' is then pulled outwardly of the chamber so as to permit thehinged drip tray 46 to slide along theflanged rails 4,0 and d i.

Furthermore, by my invention, small objects are readily and easilyrecovered during washing operations. Also, any waste or refuse materialis trapped and, by continuouswashing, is broken down into smallparticles which are easily washed oil.
